This is a completely lopsided match, clearly in Nagato's favour. Considering that fighting an alive Nagato would be problematic for even EMS Sasuke, the Sasuke who fought Danzo and Killer B would have incredibly poor chances of snatching victory in that given scenario and even worse chances in this. Nagato can easily exploit Edo Tensei's perks (such as having an undying body) and afford to tank a few Susanoo arrows or the like; it's simply not a problem since nothing in MS Sasuke's arsenal would be able to kill him (let alone seal him). Gedo Mazo alone would cause MS Sasuke serious problems as he lacks the benefits of jutsu spam which the Eternal Mangekyou Sharingan's gifts the wielder. Then of course, you have the usual Chibaku Tensei or Chou Shinra Tensei game enders.
